The present disclosure generally relates to containers for facilitating the shipping of ready meals.
Ready-to-eat meals (“ready meals”) are pre-cooked measured food portions. Cooled (e.g., frozen) ready meals may require nothing more than rethermalization (e.g., reheating) before serving. In many cases, the pre-cooked food is stored in modular food trays sealed with a removable covering film. The modular food trays are often conveniently designed to facilitate both reheating (e.g., via microwave or conventional ovens), when required, and serving. Traditionally, ready meals have been sold primarily at retail outlets (e.g., grocery stores). However, in recent years, on-demand food preparation services have entered the market, providing ready meals for home order (e.g., via shipping services).
In one or more aspects of the present disclosure, a ready-meal shipping container includes: a housing including a plurality of walls bounding an interior cavity; and a food-tray-retention assembly. The food-tray-retention assembly includes: a plurality of racks arranged in a stacked configuration within the interior cavity of the housing, each of the racks including one or more discrete bounded cells for receiving modular food trays; and an elongated sleeve aligned with the racks and configured to receive a temperature control member in a position to promote heat transfer between the temperature control member and modular food trays received in the cells. Each of the racks is configured and arranged within the interior cavity such that, during shipping operations, the modular food trays are retained in a fixed position relative to each other, the walls of the housing, and the elongated sleeve.
In one or more aspects of the present disclosure, a ready-meal shipping container includes: a housing including a plurality of walls bounding an interior cavity; and a food-tray-retention assembly. The food-tray-retention assembly includes at least one rack located within the interior cavity of the housing, the rack including one or more discrete bounded cells for receiving modular food trays; and an elongated sleeve positioned adjacent the rack and configured to receive a temperature control member in a position to promote heat transfer between the temperature control member and modular food trays received in the cells. The housing further includes a non-planar gable structure enclosing a top portion of the interior cavity.
In one or more aspects of the present disclosure, a packaged ready-meal assembly includes: a housing including a plurality of walls bounding an interior cavity; and at least one rack located within the interior cavity of the housing, the rack having a planar surface defining one or more discrete openings; one or more food trays containing pre-cooked food and positioned in the one or more openings and held spaced from one another by the rack; and an elongated sleeve spanning the rack and positioning a cooled substance in spaced relation to the one or more food trays.

The present disclosure generally relates to shipping containers for facilitating the shipping of ready meals disposed in module food trays. One or more aspects of the present disclosure are drawn from an awareness that ready meals featuring non-frozen food portions provide a substantially superior product in the eyes of consumers (e.g., better taste, presentation and nutrition) as compared to frozen food. Thus, a shipping container in accordance with one or more embodiments of the present disclosure may be configured to transport ready meals at a sustained chilled (but not frozen) temperature or at a sustained serving temperature. As used herein, the term “chilled temperature” is intended to mean that the food portions are maintained at a cool temperature above freezing (e.g., a temperature between about 40° F. and about 32° F.); and the term “serving temperature” is intended to mean that the food portions are maintained at a warm temperature of at least about 140° F.
One or more aspects of the present disclosure are drawn from a further awareness that the reheating of chilled ready meals via stovetop or conventional oven tends to provide a superior consumer product as compared to reheating by microwave. However, given a choice, many consumers may choose to microwave ready meals merely as a matter of convenience. To drive the consumer towards conventional oven heating, the modular trays containing the chilled food portions can be manufactured including a non-microwavable material, such sheetform aluminum foil or other appropriate metals, as opposed to microwavable plastic or paper. The high heat conductivity of the metalized trays may also be advantageous for facilitating heat transfer (e.g., heating or cooling) of the food portions contained therein during transport within the shipping container. The metalized trays may be particularly delicate and prone to bruising during bulk shipping due to the relatively thin walls of the structure combined with the pliable, non-elastic nature of the materials and the relative softness of the non-frozen food. Accordingly, in some embodiments, a ready-meal shipping container includes a food-tray-retention assembly including multiple racks appropriately configured to retain a plurality of modular food trays in an effectively isolated condition during shipping operations. Further, in some embodiments, a ready-meal shipping container includes a housing featuring a non-planar gable structure enclosing the top portion of an interior cavity containing the modular food trays. As discussed below, the gable structure is appropriately designed to inhibit service persons from mishandling the read-meal shipping container during shipping operations.
Referring first to
The gable structure 108 encloses the top portion of the interior cavity 105. As noted above, the gable structure 108 is a non-planar construction designed to inhibit service persons from mishandling the ready-meal shipping container 100 in a way that may damage the delicate modular food trays contained therein. In this example, the gable structure 108 includes multiple components that project vertically upward from the topmost edges of the base 106 to create the non-planar construction. In particular, we have found that the particular configuration (e.g., shapes and sizes) of the components shown and described herein tends to inhibit service persons from placing the ready-meal shipping container 100 in an improper orientation (e.g., upside down) and from stacking other packages on top of the shipping container 100.
In this example, the gable structure 108 includes two roof panels 118, two gable panels 120, and two retention panels 122. With the gable structure 108 in a closed condition, as illustrated in
The gable panels 120 are pressed together along the seam where the roof panels 118 meat to form an upstanding ridge 124, two locking tabs 126 extending vertically upward the opposing ends of the ridge 124, and a handhold opening 128 near the center of the ridge 124. In this example, the ridge 124 extends lengthwise to span the entire length “L” (see
With the gable structure 108 in the closed condition, the locking tabs 126 of the gable panels 120 are received by the slot openings 130 (see
In some embodiments, the housing 102 is formed by appropriately folding a contiguous and generally flat blank, and securing the blank in the folded condition (e.g., via mechanical fasteners or adhesive). The blank may include indented fold lines or seams to facilitate assembly of the housing 102. In some embodiments, one or more components of the housing 102 can be made from a recyclable material, such as commercial grade corrugated cardboard, paperboard and/or recyclable fibers or plastics.

As shown in
Each of the racks 202a, 202b includes a face panel 206, two opposing side walls 208, two support rails 209, a front panel 210 and a rear panel 211. The support rails 209 extend partially inward (e.g., by about 1.5 inches) in the widthwise direction of the racks 202a, 202b from the bottom edge of the side walls 208. The side walls 208, front panel 210, and rear panel 211 extend downward from the face panel 206 to partially bound a bottomless interior space 212. Thus, the cells 214 of the upper rack 202a are exposed to the underlying sleeve 204 carrying the support rails 209.
The face panel 206 of the racks 202a, 202b includes a plurality of discrete cells 214. As shown, the cells 214 are located at regular intervals along the length of the racks 202a, 202b so that the weight of the food trays 300 retained therein is uniformly distributed. In this example, the face panel 206 of each rack 202a, 202b includes three discrete cells 214. However, other configurations are also contemplated within the present disclosure (e.g., the racks may include more—e.g., four, five or six—cells or less—e.g., two or one—cells, and/or the respective racks may include a different number of cells). The cells 214 are formed as throughhole apertures bounded by the surrounding surface material of the face panel 206. Thus, the cells 214 of the upper rack 202a are exposed to the underlying sleeve 204 which carries the support rails 209 of the rack 202a.
In this example, each of the cells 214 defines a rounded rectangular shape, appropriately sized to accommodate the contour of the modular food trays 300. In some embodiments, the cells 214 have a length of between about 6 inches and about 10 inches (e.g., about 8 inches), and width of between about 3 inches and about 7 inches (e.g., about 5 inches), and the radius of the rounded corners is between about 0.12 inch and about 1 inch (e.g., about 0.5 inch). The food trays 300 fit relatively snug within the cells 214 such that lateral movement is inhibited. Thus, the food trays 300 are effectively isolated from one another and from the walls of the base 106 of the housing 102. As shown in
The elongated sleeve 204 is a rectangular shaped construction with open ends, featuring an upper surface 215 and a lower surface 216 connected by opposing side walls 218. The bounded interior space 220 of the sleeve 204 is substantially void, designed to receive an appropriate temperature control member (not shown). The temperature control member is designed to create heat transfer (e.g., conductive or convective heat transfer) with the food trays carried in the racks. In various embodiments, the temperature control member may include any suitable type of cooling element and/or heating element. In some embodiments, the cooling element may include one or more ice packs, ice blankets, ice pouches, endothermic cold packs and/or refrigerant gel packs. In some embodiments, the cooling element may include a vessel containing dry ice. In some embodiments, the heating element may include one or more exothermic hot packs and/or a battery-powered heating pad. The positioning of the temperature control member within the sleeve 204 located between the racks 202a, 202b promotes heat transfer between the temperature control member and the food trays 300 disposed in the cells 214. In this example, the temperature control member draws in heat from the bottom of the trays 300 located in the upper rack 202a and from the top of the trays 300 located in the lower rack 202b.
The use of terminology such as “front,” “rear,” “top,” “bottom,” “above,” and “below” throughout the specification and claims is for describing the relative positions of various components of the ready-meal shipping container and other elements described herein. Similarly, the use of any horizontal or vertical terms to describe elements is for describing relative orientations of the various components of the ready-meal shipping container and other elements described herein. Unless otherwise stated explicitly, the use of such terminology does not imply a particular position or orientation of the ready-meal shipping container or any other components relative to the direction of the Earth gravitational force, or the Earth ground surface, or other particular position or orientation that the ready-meal shipping container or other elements may be placed in during operation, manufacturing, and transportation.
A number of embodiments of the invention have been described. Nevertheless, it will be understood that various modifications may be made without departing from the spirit and scope of the inventions. As one example, while the illustrated examples feature a food-tray-retention assembly including two racks arranged in various stacked arrangements, other suitable configurations and arrangements are also contemplated within the present disclosure. As one example, the elongated sleeve could be positioned below the racks (e.g., if the temperature control member includes a heating element). As another example, a suitable food-tray-retention assembly may include multiple sleeves positioned between different sets of two or more racks; and/or multiple sleeves positioned above or below different sets of two or more racks. Alternatively, a suitable food-tray-retention assembly may include a single rack and a single sleeve, or a single rack with multiple sleeves, where the sleeves sandwich the single rack in the stacked configuration, a single rack with no sleeve, without departing from the scope of the present disclosure.
